What is 14x15 and what is an art teacher ordered 26 sets for class there are 100 markers in each set how many in 26 sets?

Let x be the number of weeks it will take Paul to save enough money to buy the skateboard.

In one week, Paul earns $5, so in x weeks he will earn 5x dollars.

Since he already has $25 saved, the total amount of money he will have after x weeks is:

5x + 25

To be able to buy the skateboard that costs $85, Paul needs to save up an additional:

85 - 25 = 60

Therefore, we can set up the following equation to find the number of weeks it will take Paul to save up enough money:

5x + 25 = 60

Simplifying and solving for x:

5x = 35

x = 7

Therefore, it will take Paul 7 weeks to save up enough money to buy the skateboard.

The equation that describes the number of weeks (w) that it will take Paul to save enough money to buy the skateboard is:

5w + 25 = 85

You will pay $2.90 in sales tax in California for a pair of jeans that costs $40.

At the time of sale, a tax known as sales tax is applied to the cost of products or services. The state, county, or city where the transaction occurs determines the tax rate, which is often expressed as a percentage of the purchase price. The vendor is responsible for collecting sales tax and remitting it to the relevant government body. Sales taxes are levied in order to raise money for the government and pay for essential services like infrastructure, healthcare, and education. Because it is based on the quantity of goods or services consumed rather than income or wealth, sales tax is a sort of consumption tax.

Given that, sales tax in California is 7.25%.

Thus,

Sales tax = price of jeans x sales tax rate

Sales tax = $40 x 0.0725

Sales tax = $2.90

Therefore, you will pay $2.90 in sales tax in California for a pair of jeans that costs $40.

Thus, the two digits are 9 and 11.

Two-variable equations are algebraic equations that involve two variables, typically x and y, and describe a relationship between them.

Let's call the tens digit "T" and the ones digit "O". Based on the problem, we know that:

T = 2 + O

Then substitute this equation in 10T + O = 10O + T + 27 i.e.

10T + O = 10O + T + 27

10T - T = 10O - O + 27

9T = 9O + 27

9(2 + O) = 8O + 27

9(2 + O) = 8O + 27

18 + 9O = 8O +  27

9O - 8O =  27 - 18

O = 9

Then,

T = 2 + 9

T = 2 + 9

T = 11

Thus, the two digits are 9 and 11.

The width of the rectangle is given by the expression 2x² + 5. Then the correct option is D.

Given that:

Area, A(x) = 2x³ + 6x² + 5x + 15

Length, L = x + 3

The formula for the area of a rectangle is:

A = length x width

A(x) = (x + 3) · W

A(x) / (x + 3) = W

W = (2x³ + 6x² + 5x + 15) / (x + 3)

W = [2x²(x + 3) + 5x(x + 3)] / (x + 3)

W = [(2x² + 5)(x + 3)] / (x + 3)

The equation of line perpendicular to y=x-5 passing through (-3,9) is y=-x+6.

Two distinct lines intersecting each other at 90 degrees or at a right angle are called perpendicular lines

To find the equation of a line perpendicular to y = x - 5, we need to first determine the slope of the original line. The slope of a line in slope-intercept form (y = mx + b) is the coefficient of x, so in this case, the slope of the original line is 1.

Since we want to find the equation of a line perpendicular to this line, we need to find the negative reciprocal of the slope, which is -1.

So, the slope of the perpendicular line is -1, and we also know that it passes through the point (-3,9).

We can use the point-slope form of a line to write the equation of the perpendicular line:

y - y1 = m(x - x1)

where (x1, y1) is the given point and m is the slope of the line.

Substituting the values we know, we get:

y - 9 = -1(x - (-3))

Simplifying this expression, we get:

y - 9 = -x - 3

Adding 9 to both sides, we get:

y = -x + 6

Therefore, the equation of the line perpendicular to y = x - 5 and passing through the point (-3,9) is:

y = -x + 6

So the answer is option 1: y = -x + 6.

The cost of 5 tables and 6 chairs would be Rs. 1200.

Let the cost of one table be x and the cost of one chair be y.

From the given information, we have the following two equations:

2x + 3y = 3200 ... equation (1)

4x + 10y = 3200 ... equation (2)

To solve for x and y, we can multiply equation (1) by 2 and subtract it from equation (2) to eliminate x:

4x + 10y = 3200

(4x + 6y = 6400)

4y = -3200

Solving for y, we get:

y = -800

Substituting y = -800 into equation (1), we get:

2x + 3(-800) = 3200

Simplifying and solving for x, we get:

2x - 2400 = 0

2x = 2400

x = 1200

Therefore, the cost of one table is Rs. 1200, and the cost of one chair is Rs. -800 (which means the cost of one chair is Rs. 800 with a negative sign indicating a decrease from the original cost of Rs. 1200).

To find the cost of 5 tables and 6 chairs, we can simply multiply the cost of one table by 5 and the cost of one chair by 6 and add them:

Cost of 5 tables = 5 * Rs. 1200 = Rs. 6000

Cost of 6 chairs = 6 * Rs. (-800) = Rs. -4800 (or Rs. 4800 with a negative sign indicating a decrease from the original cost of Rs. 800)

Total cost = Rs. 6000 + Rs. (-4800) = Rs. 1200

Therefore, the cost of 5 tables and 6 chairs is Rs. 1200.

What is a capacitor short answer?

A capacitor is a component used in electrical circuits to hold charges. The idea behind how a capacitor functions is that when an earthed conductor is moved close to a conductor, its capacitance increases noticeably.

                                      As a result, a capacitor contains two plates with equal and opposing charges that are spaced apart. Two conductors that are near to one another and are isolated from one another make up a capacitor, a device for storing electrical energy. The parallel-plate capacitor is a straightforward illustration of such a storage device.

We can use the continuous compound interest formula:

A = Pe^(rt)

where A is the final amount, P is the initial amount, r is the interest rate (as a decimal), and t is the time (in years). We can rearrange this formula to solve for t:

t = ln(A/P) / r

where ln is the natural logarithm function.

Using the given values, we have:

P = 920

A = 2310

r = 0.047

So,

t = ln(2310/920) / 0.047

t ≈ 18.8 years

The area of regular pentagon is 758.7 square in.(rounded to the nearest tenth.)

A pentagon is a specific type of polygon with 5 sides and 5 angles. The word “pentagon” is constructed of two words, namely Penta and Gonia, which defines five angles. So in a simplified way it can be said that pentagon is a polygon having 5 sides.

Here is a regular pentagon with side length 21 in.

Area of regular pentagon (A)= [tex]\frac{1}{4} \sqrt{5(5+2\sqrt{5} )} a^{2}[/tex]

Here a= 21 in

So Area = [tex]\frac{1}{4} \sqrt{5(5+2\sqrt{5} )} (21)^{2}[/tex] square in.

             = [tex]\frac{1}{4} \sqrt{5(5+2\sqrt{5} )} 441[/tex]     "

             ≈758.73053 square in

the recommended amount of mulch for the flower bed with a radius of 20 feet and a desired depth of 0.5 feet is approximately 628.3 cubic feet.

The given information about the vertex of the function does not appear to be relevant to the question about mulch for a flower bed. However, we can still solve the problem using the given radius of the flower bed.

The formula to find the recommended amount of mulch for a circular flower bed is:

Mulch = π * r^2 * d

Where r is the radius of the flower bed and d is the desired depth of the mulch.

Assuming a desired depth of 0.5 feet, we can plug in the given radius of 20 feet to the formula:

Mulch = π * (20 feet)^2 * 0.5 feet

Mulch = π * 400 square feet * 0.5 feet

Mulch = 200π cubic feet

To find the approximate value in decimal form, we can use the approximation π ≈ 3.14:

Mulch ≈ 200 * 3.14

Mulch ≈ 628 cubic feet

Rounding to the nearest tenth, we get:

Mulch ≈ 628.3 cubic feet

Answer:

y = 3x + 11

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 2 ) and (x₂, y₂ ) = (- 2, 5 )

m = [tex]\frac{5-2}{-2-(-3)}[/tex] = [tex]\frac{3}{-2+3}[/tex] = [tex]\frac{3}{1}[/tex] = 3 , then

y = 3x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (- 2, 5 )

5 = 3(- 2) + c = - 6 + c ( add 6 to both sides )

11 = c
